HYDBOCARBON-FUEL BURNER.

Application led November 5, 1919. Serial No. 335.914.

To all whom it may concern.'

Be it known that I, TnoMAs E. lVonTH nvu'roN, a citizen of the UnitedStates, residing at vKansas City, in the county of Jackson and State ofMissouri, have invented certain new and useful Improvements inllydrocarbon-Fuel Burners; and I do declare thc following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appcrtains to make and use thesame, reference being had to the accom panying drawings, l.1nd to theletters and figures of reference marked thereon, which form a part ofthis specification.

This in vcntion relates to hydrocarbon fuel burners and one of theobjects thereof is to provide a fuel burner in which the hydrocarbonwill become thoroughly gasified so that complete combustion will takeplace.

I have provided means whereby the liquid hydrocarbon fuel may bepreliminarily heated, if desired, to faporize it, the vapor being feddownwardly7 upon a surface, the heat from which will gasify the vaporand means is provided for supplying the requisite amount of oxygen tosupport combustion so that a very intense flame is provided, and wherefound desirable, l may utilize a heatretaining block, preferablyconsisting of asbestos or mineral wool on account of its known heatabsorption and retaining quali ties.

In the drawings,

Figure I is a perspective view of a furnace to which my invention isapplied, parts being broken away to show the position of the heater, and

Fig. 1I is a disassociated view of the several parts of the heater, and

Fig. III is a vertical, longitudinal sectional view through the heater.

Referring now to the drawings by numerals of reference:

1 designates a concavo-convex chamber having a central, upwardlyextendinof, pyramidal or conical projection 2 an( provided With a cover3 with a central opening 4, through which .the projection 2' slightlyextends. The member 1 is provided with a plurality of air ports 5consisting of downwardly projecting tubes and saidtubes discharge into acentral` space 6 formed by a cover 7 resting upon the member 1, connetedto and sniced from the cover 3, as clearly indicate in Fig. III. Thecover 7 Specification of Letters Patent.

preferably carries a scat or pan S to receive a heat-retaining block 9of asbestos or simi lar material and through which the discharge end lllof the hydrocarbon supply pipe 1l projects, the discharge end l() beingin axial alinement with the projection 2 and the supply pipe 1l havingone or more coils 12 in close proximity to the burner cover T so thatth(l heat therefrom will partially vaporize the hydrocarbon as it pathrough the pipc and allow it to bo discharged in a vapor upon the(ll-.Hector plat@l formed by the projection there being a baille orring-lil e iiangc 1S within the concavo convex member l to retard thepasu sage of the oil beyond. the base of the proV jectionV 2 but in `theevent that enough oil enters the chamber formed by the members 1 and 3,this will be taken care of by the overflow pipe 14.

From the foregoing it will be apparent that if the valve 15 is opened toadmit oil to the inner chamber burner and the same ignited, the burnerwill become heated. there being enough oil or hydrocarbon liquid retained by the ring 13 for priming purposes. W hen the heater becomes hotenough, the hydrocarbon passing through the coil 12 will be vaporizcdand will be further gasi fied upon striking the projection 2 and in-Aasmuch as there will be an ample supply of oxygen admitted through theports 5, an efficient hydrocarbon mixture will be provided to supply anintense heat, as has been clearly demonstrated in actual practice. Thearrangement shown in the drawings is such that practically no smoke orsoot forms, as the combustion of the fuel is practically7 perfect andsubstantially all of the 1". T. Il. in the fuel are generated into heatavailable from the burner.

What I claim and desire to secure by Letters-Patent is:

1. In an oil burner comprising a concave bottom having a central,opstanding, conical projection, a bafile ring about the projection, thebottom being provided with air openings, a spider-like top fitting overthe bottom and having air ports alining with the air openings, and anoil supply pipe extending through the top of the burner.

2. A burner comprising a base having an upstanding projection, a ringabout the projection, said base being provided with openin s, a chamberabove the base and havin tubular ports alining with the ports in the
